I am currently using Harmonic Tech Pro9+ but at time I feel the sound may be a little on the warm side and makes things congested with bass heavy materials. Although I don't know if it's my sytem or the cables but I am think of buying a pair of Nordost Blue Heaven to try out.
System consists of Living Voice Avatar, VTL Deluxe Mono 120, Musical Fidelity Pre24 and HT Pro Silway II.
Don't buy anything. Call The Cable Co. and get a loaner from almost any brand you can name and try them out for a week. It's the only way to go. Call 1-800-Fatwyre. I do not represent them, but have dealt with them for years.
Another option. You can also try the Ah! Direkt Cables. They are supposedly swiss made but look quite humble. However, I was stunned at how good they sound compared to cables 3 times their prices. They sound vivid (present), open (extended at both extremes), airy and fast. Music just flows...
